This invention relates to an air cushion. or mattress and has for anobject to provide an improved air cushion or mattress which is made ofpartly stuffed material and partly of a pad con 5 taining section.

A further object of this invention is to provide an air container for anair cushion or mattress, which air container is of such a shape that aplurality of cotton tufts may project therethrough.

Yet a further object of this invention is to provide an air container ormattress wherein the air container can be filled through a single valve.

Still a further object of this invention is to provide an air mattressor cushion which will consist of one or more units held together by acanvas container surmounted by an overlapping pillow and wherein each ofthe one or more units will consist of a combination of cotton tuftsinterposed between the lattice like opening in a unitary air container.

Still a further object of this invention is to provide an improvedtufting for the mattress consisting of a cotton member held together bystitching and by an elastic band.

Yet an additional object of this invention is to provide an air mattressor cushion having an air container, in which the air containerisjacketed to a limit of expansion to the desired size.

With the foregoing and other objects in view, as will hereinafterbecomeapparent, this invention comprises the constructions, combinationsand arrangements of parts, hereinafter set forth, disclosed and shown onthe accompanying drawings. Inthe drawings,

Figure 8 is a perspective view of one of the cotton tufts.

Figure 9 is a sectional view taken on line 9-9 of Figure 6, and

Figure 10 is a modification partly in section, showing two layers of aircushions.

There is shown at 10 one form of this invention shown in the form of acushion, but although the showing has been made of a pillow or cushofsame front ion square or rectangular in shape this invention may be madeup in a suitable size for use as a mattress of any desired shape, aswill hereinafter become apparent.

The cushion it consists of a canvas receptacle 69 01' bottom 11 havingan opening therethrough for an air valve 12. Secured along the sides ofthe receptacle 11 at suitably placed intervals, are fastening members 13designed to cooperate with the fastening members 14 provided onprojecting flanged 15 of a top pillow 16, this top pillow being suitablystuffed as with down or other suitable material. 1 Y

Aswill be observed. flanges 15 of the stuffed pillow 16 cooperate withthe receptacle 11 to secure therein a cushion unit or units 17 and a'mattress roll 18, a bottom padding 19 being provided between the units17 and the receptacle 11. A cover 30 on receptacle 11 is likewise heldin place by sewing 31. The cushion may contain only a single unit 17 asshown in Figures 4, 5 and 6 or may contain two units 1'7 as shown inFigure 10. It will be further understood that as many additional units17 may be provided in accordance with the thickness of mattress orcushion that is being made. Each unitl'i consists of an air pillow 20lattice like in shape, as shown in Figure 6, a plurality of cotton tufts21 and jacketing means 22 for the air pillow 20, there being a separatejacket 22 provided for each arm intersection and each border of thepillow. The air pillow 29 is a single unit consisting of a plurality ofintersecting arms 23 and 24, the valve 12 being located at theintersection of two of the arms 23 and 24. As many of these 0 arms 23and 2% will be provided as is desirable according to the size of thecushion or mattress.

Integrally connected borders 25 and 26 are likewise provided. Projectinginwardly from each of the and the borders are a plurality of fingers2'7, the fingers 27 stopping short of each other, thus providing anopening projecting through the air pillow, there being fivesubstantially separate openings provided between each four fingers 27,the openings being shown at 28.

A separate cotton tuft 21 is provided for each opening 28 in themattress, the cotton tuft 21 consisting of a tufting of cotton sewedtogether to hold its shape and surrounded by an elastic band 29, thetuft 21 substantially filling the recesses 28. The jacketing means 22consists of a piece of canvas or similar material laced about thefingers and the arms, the jacket lacing being shown at 29. The jacket 22and lacing 29 are up substantially non-stretchable, and they serve tolimit the amount that the air pillow 20 can expand when pressure isexerted therein through the valve 12, thus serving to keep the pillow inthe proper shape. After the unit 17 is placed on the padding bottom 19of the receptacle '11 the roll 18 is placed thereabout to provide asquared edge. The roll 18 may consist of a canvas tubing stuffed withcotton. The pillow 16 is then placed on top of the cushion 19, thefastenings 13 and 14 securing the flanges 15 of the pillow 16 in place,thus holding the entire device assembled. Before the air pressure isinserted, the jackets 22 may be hasted to the cover 3% as shown, toassist in keeping the cover and the jackets properly positioned. Airpressure from a suitable source is then inserted through. the valve 12,the jacket 22 serving 'to limit the expansion of the pillow arms andborders as has already been explained.

On omitting the pressure in the air pillow 20' until the device has beenassembled, it is easy to assemble the entire cushion. When two or 'moreunits 17 are provided-in order to increase the thickness of themattress, it will be found suffioient to omit inserting the pressure inthe lowermost unit 17 until after the pillow or mat tress has beenassembled.

The novel features and the operation of this device will be apparentfrom the foregoing description. While the device has been shown and thestructure described in detail, it is obvious that this is not to beconsidered limited to the exact form disclosed and that changes may bemade therein within the scope of what is claimed without departing fromthe spirit of the invention.

Having thus set forth and disclosed the nature of this invention, whatis claimed is:

1. A cushion or mattress comprising a covered receptacle, a cushionedpillow top, means on said cushioned pillow top cooperating with saidreceptacle securing said top to said receptacle, and a cushioning unitreceived withinsaid receptacle, said cushioning unit including a latticelike air illow and a plurality of tuft members within the latticeopenings in said air pillow.

2. A cushion or mattress comprising a covered receptacle, a cushionedpillow top, means on said cushionedpillow top cooperating with saidreceptacle securing said top to said receptacle, a cushionin unitreceived within said receptacle, cushioning unit including a latticelike air pillow and a plurality of tuft members within the latticeopenin in said air pillow, and jacket in" means on'said air pillowlimiting the expansion thereof.
